Answer:
Ampere's law.
Explanation:
The phenomena is known as Ampere's law.
The formula for this is an integral closed loop. The magnetic field density (B) integral along an imaginary closed path is equal to the current product enclosed by the medium's path and permeability. Line integral to the coil's magnetic field = μo times the current that passes through it. It is expressed as mathematically as - ∫ B.dl = μoI
where μo is the permeability of free space that is 4π × 10`-15 N/ A2 and
∫ B.dl is the line integral of B around a closed path.
